Nipple downblouse
From Voyeurweb's Wiki about Sex
The nipple downblouse is a special type of downblouse. It requires to spot a girl in a lucky downblouse where you can see/photograph her top down all the way to her nipples. In many cases nipple downblouse opportunities occur mostly on braless girls, which means most nipple downblouse shots are braless downblouses as well. It is more likely to see a nipple downblouse on a girl with smaller breast size.
